Hello everyone,

I have a project about fuel injector (200-350bar) testing bench and first assessment is to find different solutions of common rail direct injection system for gasoline engines. I'm really struggling to find any informations about any variations. I found few engines that are using that system but can't find some sort of handbook. Can someone help and give me some advice where or how I can finde this type of informations.

Thanks in advance

I’m a sophomore at a big public university. I’m working on my reqs right now and I’m taking differential equations. The Professor is really disorganized, and is lacking in English. I’ve been skipping classes and only going on exam days. I’ve done well on both exams with A’s on both, but I feel guilty for skipping out on my paid education. How much am I shooting myself in the foot for this.

To make it short, I don't live in the US so it's a pretty different system from there.

I just turned 26, started school again 2years ago (lots of reasons) and managed to get my diploma sadly the stuff I learned isn't enough to follow directly into the 3years of engineering school.

I'm currently in a preparation school, it's like lots of materials condensed over 6-7months to be ready before engineering.

I just got diagnosed with adhd over a month ago and my biggest problem is a very very severe executive dysfunction as I almost can't do anything at all most days, even watching a show or playing games is a difficult task.

I never ever studied either and because of executive dysfunction I cannot even sit down and atleast just start.

I started over a month ago now, currently last day of 2weeks vacation, I ready forgot everything, I didn't do any of the homework.. I understand everything we do in class but I just cannot put in the work to remember and actually learn stuff.

I was thinking of taking a break and to start again next year so I can get medication sorted and more.

I love what I'm learning, I really wanna be an engineer and work in robotics but I just can't bring myself to do anything even hobbies, I love drawing but drew 6time in 10years and I'm not exaggerating and this is just one example.

I feel really bad for " giving up " again for " being lazy " and for " not wanting it enough " as peoples says, I feel crazy as no ones seems to get it even other people I know that have adhd.

It's like I'm just watching time pass by and I can't do anything about it and actually physically don't do anything.

I’m a third year junior in AE. Tbh, this semester has been challenging, academically and mentally. I’m taking thermodynamics and for sure I most likely gonna fail this class and I already accepted this. Physics II has been tough and I have a midterm in 2 days that I’m feeling not too positive about. I’m doing ok in my other classes tho, but man this semester has been draining.

Is Junior year really the hardest year? Does senior year get somewhat better? Tbh I feel ashamed for feeling like this. I spoke to my parents about how I feel and they understand. Sorry for venting, but I just needed to let this out.

This topic is going to be my 13th reason on god.

To clarify: Taking statics rn (first semester), everything else about this course is either: A) stuff I’ve seen before B) stuff I can reliably predict the answer to.

But this godforsaken topic just appeared on my second midterm and Im pretty sure I completely missed the right answer. I wasnt oblivious to my weakness regarding this topic, but each problem in this category seems to have no real correlation with the other ones.

guess I just needed to vent lol. If yall have any advice that would be greatly appreciated.

wonder if anyone has any suggestions that person do, when i is not able to find a job. even though we have all the skills that we requied... connection that we have .... and still.... I been finding a job since last 6-7 month, doing interviewing and keep getting noting....

Title. About 10% of people worldwide are left handed, yet about 90% of the people in my engineering cohort are left handed, including myself. What is your experience? Is this a trend, or is it just a weird coincidence? I've seen there's a little bit of research to suggest engineers have a higher percent of left handed people.

Basically title. I need to make precision cuts on a 1/16 or 1/8 inch thick piece of flexible graphite with stainless steel insert so that I can turn it into a flange gasket. Of course I can order it custom but that would be way more money than I want to spend. Any ideas are appreciated thank you!

Currently, I’m in my final year of engineering and I’m having a job offer for a QA role. I’m looking forward to switch from QA to SDE, how difficult is that?? What skills are to be gained to do so? Also, I’m planning on doing Masters in USA. Are there enough opportunities as a QA engineer in USA, also what’s the difficulty of having a transition from QA to SDE in India compared to USA.

Open for suggestions and also let me know future opportunities which would beneficial if I choose to continue with QA role.

I live in Germany and right now I do my Master in aerospace engineering. I would like to get some recommendations for good paying and encouraging companies where I can start when I finish my studies.

I'm the only one who failed the class(below 40) while the average score is B+. I am too scared that someone will find out. Why is it too easy for others but too difficult for me? I am having mental health, and I can't learn and absorb anything. I don't understand anything what is going on in all of my classes.

Hi i m international student just came this fall and really facing problems due to many things please suggest some tools so i can relax my study

Hey all.

I am an older person returning to college after a few years of the workforce. I was just wondering if I could get some advice/insight on this situation I'm in.

Most of my time in college has been fine, I've been able to maintain a mostly A to B average throughout. However, I find myself struggling in groups because I feel so distant from the young adults I am grouped with. Often, this isn't a problem, but sometimes I just seem to find myself in weird circumstances.

I present to you my current predicament:

I am in a group of three. These labs require a lot of programming. One of the group members, just creates the document on google drive, and I swear, I have not once, ever seen them do any kind of coding. We are sitting in front of the school computers, they could easily log in and do some. Instead, they just kind of sit there, copying and pasting the wording from the instructions on their tablet. The other, they do coding, but don't leave any work for the other person, and are always questioning me about my work.

I just... I feel like I should know how to deal with this situation, since I'm older, but like I am not these people's parents? The person that questions me all the time, I made a few mistakes throughout the course, that they found. I reworked the math to find that I indeed made a mistake. However, I occasionally will find something wrong that the same member did, I will gently suggest that it could wrong. I will then, go through the work and show them the equations and graphs I used. Both of them will agree with each other that the wrong answer is correct, and will not show how to answer it, just that they feel it is correct. But the other person that's agreeing didn't even do any programming?

And like, I don't know how to explain this next one, but a couple times when I have suggested something may be wrong, they will bring the teacher over, ask a series of questions that are kind of related but not directly asking about the problem at hand. The teacher agrees with these vague questions, and they take that to mean they are right? I don't know if I'm describing it correctly.

I just don't know what else to say, it just feels weird. I know that people make mistakes it's fine, but when the one member is constantly asking if I'm sure something is right, I always respond, "I did the work, I think this is correct" But the constant badgering is really eating away at my confidence. I don't do this to them, I don't know why they are doing it to me. Also, I don't know why I am getting asked these questions when the other group member isn't even doing any of the lab.

I have been doing really well in this class, I actually got a 100 on my midterm for the first time in a few semesters. I go home and do the entire lab by myself just so I can practice it, and only submit the parts I said I would work on. My current train of thought is that this is not the norm of engineering, people for the most part will be good intentioned and willing to admit mistakes. Second, that this group will eventually be over in the winter and these two won't be my problem anymore.

*edit - i forgot, my new plan is to just not to point out their errors and just let it be because dealing with them is upsetting me.

Does this seem appropriate, or should I be handling these situations differently?

Soooo I need some advice. I am going back to engineering after giving up. I took Calc II 7 years ago and it looks like I’ll have to take Calc III next Spring. I completely forgot Calc and I just want to somewhat prepare for what I’m about to get into. Thank y’all in advance.

Edit: Thank you all for the great advice, the sound of Calc III feels less daunting. Just gotta put the work in now.

Hello I hope you`re having a wonderful day!

I've entered my engineering masters this fall (still doing post-bacc credits) and am interested in graduate research positions/internships. The only issue is that I`ve been out of science, engineering and academia for about 8 years. I was a teacher/musician/small business owner in that time and developed a plethora of soft-skills, but have not kept up with any technical skills.

I`m trying to figure out how to get on the right track with this and spin it in a good light? I've emphasized my business, communication, and leadership skills. I was a great student in undergrad and had some decent lab skills. Should I still put down my analytic chem skills even though I haven`t used them in years?

Anyone in a similar position and using engineering as a (third) career change?

Any advice is appreciated, thanks so much.

Hey folks ... I'm trying to design a plan for stopping erosion on a steep river bank ...

Here's a pic of basically what it looks like. I'm just wondering, if we looked at a force arrows analysis, is the rock exerting any kind of resistance to the buoyancy of the top log? I would imagine a log that's smushed between a giant boulder and the streambank won't float as easily, but the sources I've looked at don't talk about this... Is there any friction? What do we think?

(Also we're trying to do this without any cables/ropes so I can't just tie the log to the boulder in front of it.)

Thanks, have a nice day :)

I’m curious—what’s the biggest challenge you face when studying from your notes? Whether it’s organising them, finding key information, or just retaining everything, I’d love to hear!

I’m developing a new tool to tackle these exact issues. It’ll let you upload photos of your handwritten notes, automatically turning them into organised, searchable text for easier studying. To make sure this tool is genuinely helpful, I’d love some feedback from students.

Would you take 2 minutes to share your thoughts? Your insights will directly shape the features, so it’s truly something students need.

Thanks so much!

So im a CE 3rd year undergrad. I have a 2.8 rn and im kind of stressing based on what I've recently heard that if you graduate under a 3.0 you're basically not considered by companies any may struggle a lot to find a job. Can anyone give insight on this? I live in SoCal btw if that makes a difference. And I still have like 4-5 semesters left to raise the gpa but i just want to know about this claim.

I’m mechatronics engineer student my current GPA is 2.2 will i be able to find a decent job?

So this is how it goes. Pur professor splits up the grading method for our class.

40%Lab 30%Exams 10%Attendance And 20% Quizzes

But instead of following the usual rubric(above) he decided to match the percentage of the quizzes on the same percentage of the exams. At first we thought it would be fine because he teaches us so well. Until our first quiz came only 4 students scored on the quiz and the rest of the class including me got a 0 out of the quizzes. We decided to properly study for the next quiz and he decided to amp it up to a 1hour quiz for 2 circuits using nodal and mesh analysis each. This would mean that we have atleast 30 minutes each and after the quiz NONE OF US GOT A SCORE! He already said that he got the "blessings" of our program head to "reap" the best of the best students. I can't keep up with exam going next week how are we supposed to pass if he boasts that almost every quiz most of his students get zeroes or failing scores to exams barely making 10 students pass the exams. That's all Im ready to repeat circuits 1 ffs.

This means that 1 failed quiz is the equivalent of failing our midterms/finals which is a HEAVY toll on our grades.

Hello everyone!

I'm desperate for some study help! Does anyone have reliable cheat sheets for Geometry (conic sections), Trigonometry, Unit conversions and Calculus

I'm talking lifesaving resources here! If you've got a trusty cheat sheet or know of an amazing online resource, please share!

I'd be forever grateful!🥺

Edit: If you've got a specific format or type of cheat sheet, feel free to share that too!

I’m currently pursuing an MEng in Mechanical Engineering at Western University and am also working on developing my programming skills through self-study. My goal is to transition into a software development role after graduation, and I’m building up my knowledge of programming languages, especially Java, and software development concepts on my own.

For those of you in the field, do you think a combination of an MEng degree and self-taught skills could be enough to break into a software developer role? If so, any advice on what specific skills or projects to focus on would be hugely appreciated. I'd also love to hear success stories from others who transitioned into software without a traditional CS degree.

Thanks in advance for any insights or tips!

Hi im currently a fresh graduate of manufacturing engineering technology here in ph. what the step by step process to beocme manufacturing engineer?

Hello, I'm an international freshman studying Engineering Technology and deeply in love with the BME sector (Hope to do graduate study in BME). So far I have been applying & searching for BME internships and have been either rejected or got no response. (Many don't accept F-1 visa students) I don't exactly have any Engineering-y skills apart from working in my church technical and media departments. Does anyone have tips on maybe what to do? Where to search? Conferences to attend to gain experience and so on....? I actually don't know what I am doing. P.S. I'm deeply interested in medical devices for now, but also looking at other BME sectors that intertwine with electrics like bionic, bioelectronics, neural imaging, etc

I failed all of my midterms, literally, all, and I feel so stupid, I’m a sophomore, majoring in computer engineering, and now I’m thinking of switching majors. I study so hard, for very long hours yet I don’t see any results, it’s like all of my hard work just goes into vain. I had the best grades in high school, and I know you can’t compare school life with uni life, they’re two different environments, but it feels like such a slap in the face to go from a straight A student, to a barely passing student. I don’t know what to do, should I stay in engineering and push through, or should I just drop out and switch majors? Please if anyone has gone through a similar experience, or if u have any advice please share? Cuz I’m very hopeless at the moment.

I'm a high school senior interested in engineering, and I’d love to get hands-on experience to build my skills and boost my college applications. The thing is, I don’t have much to spend on tools or materials. I mostly have basic tools and some old parts lying around (like an old Xbox controller, random wires, and bits of electronics).

I’m looking for:

Project ideas that use minimal resources but teach core engineering concepts (electronics, programming, mechanics, etc.).

Creative ways to repurpose old electronics or household items—anything I might overlook that could work as components for projects.

Learning resources geared towards beginners with limited access to professional tools. I’m hoping for tutorials or guides that are simple but still pack a punch for a college portfolio.

If anyone has experience building projects on a budget or ideas on where to start, I’d really appreciate the advice! Thanks a lot for helping me take my first steps into engineering!

Hi guys!! I have 2 whole weeks left until my midterms and I am so scared. I have been studying since the start and I don’t really have a lot of catching up. But for some reason I still feel like i need to study more because even though I study for 4-6 hours a day, it is really not that effective. I use pomodoro timer, put my phone away, use AI for help but I still feel like I don’t put my 100% focus on my studying. Any advice on how to have more effective studying? Thanks!

Hi I just started robotics engineering and had an extremely rough start. With 2 deaths in my family and just gone through depression. I have been at most lectures and delivered most assignments for the courses. However I have been extremely bad to do my homework and poor at note taking. I feel like I am almost 2 months behind. And I am in a bad cycle of feeling behind which makes everything overwhelming.

Is there hope? A plan I can follow some advice
